Document Type and Number:
WIPO Patent Application WO/2019/214276
Kind Code:
A1
Abstract:
A reflector adjustment mechanism comprises a fixing support (100), a first adjustment member (300), a second adjustment member (200), and a fixing screw (230) that matches fixing holes (201, 202). The fixing support (100) is used to mount a reflector (400). The first adjustment member (300) is provided with a first fixing contact (301), and the first adjustment member (300) is connected to the fixing support (100). The second adjustment member (200) has two second fixing contacts (240) that are separated from each other. The second adjustment member (200) is provided with the fixing holes (201, 202) and adjustment holes (203, 204), and the adjustment holes (203, 204) are strip-shaped holes. The fixing screw (230) is used to detachably fix the second adjustment member (200) to the fixing support (100). The reflector adjustment mechanism uses the adjustment holes (203, 204) to precisely adjust the longitudinal and lateral position of the fixing contact (240) on the second adjustment member (200), such that the position and the angle of the reflector (400) are changed. A projection device (10) applying the reflector adjustment mechanism enables quick and easy adjustment of the reflector (400).
